"Magnet shear to direct pull work ratio"

[Floor]

Not done.
  Still here.

Why ?

   Back face / far field interaction...

               OK to start at 6 min 05 seconds

Should use cube or bar magnets as recommended  in the "EDEN project" PDF,

    @ https://slideplayer.com/slide/3989835/

rather than wafer shaped ones...
                     and  / or use a longer out put stroke

Please Keep in mind that...

there are numerous ways in which I am not following the parameters
met in the Kedron Eden project PDF.

So, we cannot consider this present endeavor as a replication nor as an invalidation
of that other project.

Note..

One of the reasons that this method interests me, is that it functions
in attraction modes.   

This means that even when using ceramic magnets, one might get a long life
expectancy from the magnets.

Utilizing a longer out put stroke would decrease the input needed
to move from position two to position three and also increase the
output in moving from position three to position four.

For this reason and....

if / when, the magnets used were to be of cube shape, as in the Eden
project PDF, it looks like a net gain is possible here.

OK...
we got it ...
